Upon completion of a monitoring well installation, or when conducting soil borings, Laurel's United States Environmental Protection Agency (USEPA) and Occupational Safety and Health Administration (OSHA) trained staff utilize state-of-the-art sampling equipment to collect a representative soil and groundwater sample.
Groundwater depths and product thicknesses are determined using an oil/water interface probe. Wells are developed using a bladder pump and a turbidity (a measure of the silt present in water) of 50 nephelometric units (NTU's)or less to ensure proper hydraulic connection with the surrounding aquifer.
Prior to sampling groundwater, wells are purged of three to five times the volume of standing water to ensure collection of a representative sample. Samples are procured using Teflon™ bailers and transferred directly into appropriate sampling containers to eliminate the possibility of cross contamination.
Soil samples collected during drilling of monitoring wells or hand auguring of borings are characterized under the unified soil classification (USCS). An on-site Photoionization Detector (PID) analysis of the vapors present in the head space of the samples can give an initial indication of volatile organic contamination. Laurel uses this field test to aid in selecting hot samples from a site suspected of having volatile organic contamination, thereby cutting down the costs of laboratory analysis.
The samples that have been selected for analysis are sent to a National Environmental Laboratory Accreditation Program (NELAP) qualified laboratory and analyzed for the associated chemicals of concern. Laurel receives the laboratory data, analyzes the results, and concludes appropriate recommendations on how to most effectively and efficiently proceed.

If contamination is discovered, LAUREL can design and optimize an economical mitigation plan that is environmentally sound. In some cases, early implementation of a proactive remedial strategy will permit a property transaction to move forward while a clean-up is in progress.
When there is suspicion of contaminated soil or contaminated groundwater at a site, sampling and analysis must be completed to confirm the presence or absence of the suspected contaminants. This is achieved through the installation of groundwater monitoring wells and sampling of soil from cores.
The validity of the results obtained through this sampling relies heavily on the proper placement of monitoring wells and soil borings, though the placement is largely subjective. It is therefore important for a highly skilled scientist to conduct research on site history and visual reconnaissance in formulating a plan, and final decision of proper placement of the monitoring wells and borings to obtain relevant samples.
Whenever possible, LAUREL makes every effort to limit costs, damage to property and especially disruption of business, through the use of the latest state of the art drilling and sampling equipment available.
DATA COLLECTION
Correct media sampling methods are just as important as proper well installations and sampling point decisions. Utilizing the correct sampling equipment and decontamination techniques, LAUREL ensures that no cross contamination has occurred. Without exception, only properly trained and certified staff collect samples.

GROUNDWATER/SOIL SAMPLING AND ANALYSIS
Groundwater depths and product thicknesses are determined using an oil/water interface probe. Wells are developed using a bladder pump, to a turbidity (a measure of the silt present in water) of 50 nephelometric units (NTU's), or less to ensure proper hydraulic connection with the surrounding aquifer.

SAMPLING
LAUREL has found that septic systems, and industrial and storm water leaching pools are often receptors of significant contamination at any given property. By design, these systems leach as much water as possible into the ground.
GEOPHYSICAL SURVEYS
LAUREL conducts geophysical surveys to aid in the discovery of underground storage tanks, buried drums, fill material, unexposed drywells and large scale subsurface hydrocarbon contamination with no excavation or drilling necessary.
